Implantation Tuberculosis of Thyroid Gland Following Fine Needle Aspiration Procedure: A Rare Clinical Presentation: A Case Report

Implantation TB of thyroid gland following fine needle aspiration procedure: A rare clinical presentation

Abstract

A 55 year female patient presented with thyroid swelling. After initial Fine Needle Aspiration Cytology (FNAC) the swelling gradually increased in size, painful and associated with fever, the site of needle prick done for FNAC, had persisted without healing for nearly two months. Subsequently she developed multiple small swellings on right side of neck. Histopathology examination after near total thyroidectomy revealed sinus tract in thyroid lined by tuberculous granulation tissue, adjacent thyroid gland showed granulomatous thyroiditis with rest of the thyroid gland showing features of colloid goiter. Lymph nodes showed feature of caseating epithelioid cell granulomatous lymphadenitis. Suppuration after FNAC, histopathology showing localized sinus tract in thyroid lined by tuberculous granulation tissue with rest of the thyroid showing features of colloid goiter, all correlate with direct implantation.
